How is sound produced?
Vibrations
What is a medium?
States of Matter (solid, liquid, gas)
What is pitch?
How high or low a sound is
What is frequency?
Number of wavelengths that determine pitch (how high or low a sound is)
Which number represents a wavelength?
1
What is the best medium for sound to travel?
Any solid mediums
What does amplitude determine?
volume
High pitch sound have (more/less) waves per second
less
If a compression wave have a high frequency then it has a (high/low) pitch
high
If a compression wave has a low frequency, then it has a (high/low) pitch
low
What does it mean to transmit sound?
To produce sound or vibrations
How do musical instruments create sound?
through vibrations
Which image represents a sound wave?
Bottom: longitudinal wave
What are the three types of matter that sound can be transferred through?
Solid, liquid, gas
faster
Choose all the objects that will make sound transfer the fastest.
Wooden table. Balloon
Pond Oxygen
Concrete. Propane tank
wooden table and concrete
What is one reason why a guitar can produce different pitches?
The body is hollow, the size of the strings, how tight the string is
Why is there no sound in space?
There are no mediums for sound to travel through.
There is no air or matter in space
Molecules in the air are far apart/less dense. This means that sound travels...(faster/slower)
slower
Because the molecules are farther apart
What occurs when you place a vibrating tuning fork in water? Does it make ripples, a splash, or nothing occurs?
ripples
Sound is a form of what?
energy
To produce sound you start with (mechanical/sound) energy, that transfers to (mechanical/sound) energy.
1. mechanical 2. sound
What is transferred when sound transmits through the air?
a. volume
b. pitch
c. energy
